[0002] Most of the existing adjustable-height shower devices adopt a threaded locking structure. When adjusting the height of the horizontal pipe and the shower head, the nut or screw needs to be loosened, and then tightened again when the appropriate height is adjusted. When there are large differences in the heights of family members, in order to achieve the best shower effect, it is necessary to adjust every time during use, which is time-consuming and inconvenient to use.

[0003] Among the existing patents, the Chinese patent document with the application number 202021093806.7 discloses an adjustable-height shower column, including: a first water outlet pipe; a second water outlet pipe, the second water outlet pipe is sleeved outside the first water outlet pipe, and the first water outlet pipe can reciprocate along the second water outlet pipe. At least one telescopic pipe is arranged in the second water outlet pipe. The top end of each telescopic pipe is communicated with the first water outlet pipe, and the bottom end of each telescopic pipe is fixed to the second water outlet pipe; a locking assembly, the locking assembly is arranged on the second water outlet pipe and can lock and unlock the relative positions of the first water outlet pipe and the second water outlet pipe; the locking assembly includes a base, a slider, two locking blocks and a locking pin. The base penetrates through the fixed outer shell, and the base is sleeved and connected at the joint of the second water outlet pipe and the first water outlet pipe. The slider is sleeved outside the base on one side of the first water outlet pipe and is connected to the fixed outer shell. A gap is arranged between the slider and the base. The two locking blocks are oppositely arranged in the gap. Each locking block can penetrate through the base and abut against the first water outlet pipe. The locking pin can penetrate through the fixed outer shell and one side of the slider and abut against the locking block on the same side; the slider is sleeved outside the base, and wedge-shaped structures are arranged on the opposite side walls of the slider. A through hole for the locking pin to penetrate is arranged on one side wall, and the through hole and the locking pin can be threadedly connected; the locking pin is in a boss shape, and the boss includes a left part of the boss and a right part of the boss. The end face of the left part of the boss abuts against the locking block, and the left part of the boss is provided with threads; the right part of the boss penetrates through the fixed outer shell, and an operation hole can be arranged on the end face of the right part of the boss. An external fitting can be inserted into the operation hole to rotate the boss to control the position of the boss, so as to control the distance between the two locking blocks. The structure of the locking assembly of this patent document is complex. When locking and unlocking, an external fitting (auxiliary tool) is required to screw the locking pin, so that the height adjustment is inconvenient. Therefore, the defect is very obvious, and a solution is urgently needed. Summary of the Utility Model

[0020] For the convenience of understanding by those skilled in the art, the present invention will be further described below in conjunction with embodiments and drawings. The content mentioned in the implementation mode does not limit the present invention.

[0021] As Figures 1 to 5 shown, an adjustable-height shower device provided by the present invention includes an outer tube 1, an inner tube 2 slidably inserted at one end into the outer tube 1, a sewer pipe joint 3 installed inside the bottom end of the outer tube 1, a medium water pipe joint 4 installed inside the bottom end of the inner tube 2, a gravity balance mechanism 5 built inside the inner tube 2, a telescopic water pipe 6 installed between the sewer pipe joint 3 and the medium water pipe joint 4, a water supply pipe joint 7 installed inside the top end of the inner tube 2, a connecting water pipe 8 installed between the medium water pipe joint 4 and the water supply pipe joint 7, a horizontal pipe 9 installed at an angle at the top end of the inner tube 2, a horizontal water pipe assembly 10 arranged inside the horizontal pipe 9, a wall base 11 sleeved outside the top end of the outer tube 1, and a bushing 12 arranged between the wall base 11 and the top end of the outer tube 1. One end of the horizontal pipe 9 away from the inner tube 2 is used for installing a shower head. Both ends of the gravity balance mechanism 5 are rotatably connected to the medium water pipe joint 4 and the sewer pipe joint 3 respectively. The bushing 12 is sleeved outside the inner tube 2, and there is a swing gap 13 between the inner wall of the bushing 12 and the outer wall of the inner tube 2 for the inner tube 2 to swing. There is also a swing gap 13 between the inner wall of the outer tube 1 and the outer wall of the inner tube 2 for the inner tube 2 to swing. The horizontal pipe 9 extends to one side of the front of the inner tube 2. An elastic friction pad 14 is arranged on the back of the inner tube 2, and the elastic friction pad 14 is used to abut against the inner wall of the outer tube 1. A lifting groove 15 is opened in the middle of the outer tube 1. The inner tube 2 is connected with a handle 16, and the handle 16 extends out of the outer tube 1 through the lifting groove 15. The handle 16 is slidably arranged in the lifting groove 15; specifically, the horizontal pipe 9 is perpendicular to the inner tube 2.

[0022] In practical applications, the wall base 11 is bolted to the wall, the downpipe joint 3 is connected to the water supply source, and the downpipe joint 3, the telescopic water pipe 6, the middle water pipe joint 4, the connecting water pipe 8, the upper water pipe joint 7, the transverse water pipe assembly 10 and the shower head are connected in sequence; when the horizontal pipe 9 and the shower head are maintained at the use height, the gravity balance mechanism 5 supports the inner pipe 2, the horizontal pipe 9, the shower head, etc., and increases the damping force when maintaining the use height of the horizontal pipe 9. At the same time, the inner pipe 2 will swing under the action of the gravity of the horizontal pipe 9 and the shower head. The front side wall of the inner pipe 2 will abut against the front inner wall of the bushing 12. The bushing 12 serves as the fulcrum of the inner pipe 2, the horizontal pipe 9 serves as the force arm, and the elastic friction pad 14 on the inner pipe 2 abuts against the back inner wall of the outer pipe 1. The acting force applied to the inner wall of the outer pipe 1 through the elastic friction pad 14 is used to increase the damping friction force, so that the horizontal pipe 9 can be stably maintained at the required use height. When it is necessary to adjust the height of the horizontal pipe 9, an upward or downward acting force is applied to the handle 16, and at the same time, a little pulling force is applied outward (towards the front direction of the outer pipe 1) to be able to correct the inclined inner pipe 2 to a vertical state to a certain extent, which will make the damping friction force to be overcome smaller, so that the inner pipe 2 can move up and down relative to the outer pipe 1 easily. During the relative movement of the inner pipe 2 and the outer pipe 1, the telescopic water pipe 6 makes an adaptive telescopic movement. After the height adjustment is completed, just release the handle 16 to keep the horizontal pipe 9 and the shower head at the required use height. Among them, the gravity balance mechanism 5 can make an adaptive swing with the swing of the inner pipe 2, making the gravity balance mechanism 5 inclined, thereby changing the direction of the supporting force of the gravity balance mechanism 5, and further making the elastic friction pad 14 contact the inner wall of the outer pipe 1 more closely, increasing the damping friction force when the horizontal pipe 9 maintains the use height, and being more conducive to the horizontal pipe 9 being maintained at the use height. The utility model can easily adjust the height of the horizontal pipe 9 only by lifting the handle 16, has simple operation and convenient use, and the horizontal pipe 9 can stay at any use height, and has good working stability.

[0023] In this embodiment, the gravity balance mechanism 5 includes a gravity balance main body 17 and two rotating joints 18 respectively arranged at both ends of the gravity balance main body 17. The middle water pipe joint 4 and the downpipe joint 3 are both provided with transfer grooves, and the two rotating joints 18 are respectively rotatably connected to the transfer grooves of the middle water pipe joint 4 and the downpipe joint 3; the gravity balance main body 17 is a hydraulic support rod or a gas spring, and the cross-sectional shape of the rotating joint 18 is spherical or hemispherical. This structural design enables the gravity balance main body 17 to make an adaptive swing with the swing of the inner pipe 2, making the gravity balance main body 17 inclined, thereby changing the direction of the supporting force of the gravity balance main body 17, and further making the elastic friction pad 14 contact the inner wall of the outer pipe 1 more closely, increasing the damping friction force when the horizontal pipe 9 maintains the use height, being more conducive to the horizontal pipe 9 being maintained at the use height, and being able to reduce the assembly difficulty of the utility model to a certain extent.

[0024] In this embodiment, the telescopic water pipe 6 includes a movable water pipe 19 and a fixed water pipe 20. The top end of the movable water pipe 19 is installed on the middle water pipe joint 4, the bottom end of the movable water pipe 19 is slidably inserted into the top end of the fixed water pipe 20, the bottom end of the fixed water pipe 20 is installed on the lower water pipe joint 3, and the bottom end of the movable water pipe 19 is hermetically and slidably connected to the fixed water pipe 20 via a sealing structure 21; both the movable water pipe 19 and the fixed water pipe 20 are rigid pipes. With this structural design, the telescopic water pipe 6 has good telescopic stability and a long service life; among them, since the movable water pipe 19 and the fixed water pipe 20 have a certain length and certain flexibility, the movable water pipe 19 and the fixed water pipe 20 will not interfere with the swing of the inner pipe 2.

[0025] In this embodiment, the sealing structure 21 includes a sealing groove recessed outside the bottom end of the movable water pipe 19 and a sealing ring 22 fitted in the sealing groove. The sealing ring 22 is used to seal the gap between the movable water pipe 19 and the fixed water pipe 20, and the sealing ring 22 is slidably connected to the inner wall of the fixed water pipe 20. With this structural design, it not only ensures that the movable water pipe 19 can telescopically move relative to the fixed water pipe 20, but also ensures the sealing between the movable water pipe 19 and the fixed water pipe 20, preventing water leakage. In addition, when the horizontal pipe 9 is maintained at the use height, the sealing ring 22 can provide a certain damping friction force, which is more conducive to keeping the horizontal pipe 9 at the use height.

[0026] In this embodiment, the lifting groove 15 is located on the back surface of the outer pipe 1, and the handle 16 is bent and extended from the back surface of the inner pipe 2 to the outside of the front surface of the inner pipe 2. With this structural design, the lifting groove 15 is close to the wall, and water is not easily introduced into the outer pipe 1 from the lifting groove 15, and it is convenient for the user to operate the handle 16.

[0027] In this embodiment, both the outer pipe 1 and the inner pipe 2 are square pipes. With this structural design, relative rotation between the outer pipe 1 and the inner pipe 2 is avoided, and they play a guiding role for each other during the lifting process, improving the working stability of the present utility model.

[0028] Specifically, the lower water pipe joint 3 is provided with a drain hole communicating with the inner cavity of the outer pipe 1. When water enters the inner cavity of the outer pipe 1 from the lifting groove 15, the water will be discharged from the drain hole, preventing water accumulation in the outer pipe 1.

[0029] Specifically, the horizontal water pipe assembly 10 is composed of a water pipe and a joint, which will not be elaborated here.

[0030] All the technical features in this embodiment can be freely combined according to actual needs.

[0031] The above embodiments are the preferred implementation solutions of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present utility model.
